"Oh, it was simple enough! The church has a clock, facing the north, of which we could not see the dial, where we were. From the inside, our friend worked the hands so that the big hand, resting by turns on three or four figures, announced the exact distance at which we were from the church, in the direction pointed by the vane. This is what I next did myself; and the enemy at once, redirecting his fire by my indications, began conscientiously to shell the beet-field." "He did," said the colonel, laughing. "All that remained for me to do was to move on to the other observation-post, where the spy's messages were received. There I would learn the essential details which the spy himself did not know; I mean, where the enemy's batteries were hidden. I therefore ran to this place; and it was only on arriving here that I saw those batteries and a whole German brigade posted at the very foot of the church which did the duty of signaling-station." "But that was a mad piece of recklessness! Didn't they fire on you?" "I had put on the spy's clothes, sir, _their_ spy's. I can speak German, I knew the pass-word and only one of them knew the spy and that was the officer on observation-duty. Without the least suspicion, the general commanding the brigade sent me to him as soon as I told him that the French had discovered me and that I had managed to escape them." "And you had the cheek . . . ?" "I had to, sir; and besides I held all the trump cards. The officer suspected nothing; and, when I reached the platform from which he was sending his signals, I had no difficulty in attacking him and reducing him to silence. My business was done and I had only to give you the signals agreed upon." "Only that! In the midst of six or seven thousand men!" "I had promised you, sir, and it was eleven o'clock. The platform had on it all the apparatus required for sending day or night signals. Why shouldn't I use it? I lit a rocket, followed by a second and a third and then a fourth; and the battle commenced." "But those rockets were indications to draw our fire upon the very steeple where you were! It was you we were firing on!" "Oh, I assure you, sir, one doesn't think of those things at such moments! I welcomed the first shell that struck the church. And then the enemy left me hardly any time for reflection. Half-a-dozen fellows at once came climbing the tower. I accounted for some of them with my revolver; but a second assault came and, later on, still another. I had to take refuge behind the door that closes the spire. When they had broken it down, it served me as a barricade; and, as I had the arms and ammunition which I had taken from my first assailants and was inaccessible and very nearly invisible, I found it easy to sustain a regular siege." "While our seventy-fives were blazing away at you."
